LOCOMOTIVE SMOKE-BK AND SADDLE CONSTRUCTIONS.

riginal application led. March 5, 1925, Serial No. 13,242. Divided andthis application filed April 2,

This invention relatos to a novel locomotive smoke-box saddleconstruction. 'lhe invention will be best understod by reference to thefollowing description, when taken in connection with the accompanyingdrawings oit' one specific embodiment thereof,y While its scope will bemore particularly pointed ont in the appended claims,

ln the drawings:

Fig. l is a central, vertical, longitudinal, sectional view ot' aportion ot the iront end of a locomotive, including` the cylinder saddleand the smoke boi; thereon; and

Fig'. 2 is a bottom plan ot a portion ot of a locomotive, including thecylinder saddle and the smoke box thereon; and.

lerlerring,` to the drawings, and to the cnibodiment oi'` the inventionwhich is selected for exemplilication, and having reference moreparticularly to Fig. l, the locomotive,

has a cylinder' saddle Qt), which presents a support for a smoke boi;2l. Relative displacement oli' the smoke boi; and the saddle in ahorizontal direction `is prevented by interengagement ot these parts,Which prevents the attaching,` bolts from beine,V subjected to anyshearingstresses.

In the present example, this is conveniently accomplished by providing'the smoke boi: with iront and rear abntinents, presented by depending'flanges 22, which receive the forward and backward thrusts, said smokeboi; presentingl similar side lianges 23, which receive the sidethrusts, all ot which tianges embrace a seat 24, presented by thecylinder saddle. i-lerein, the seat is tlat,-that is to say, it is aplane horizontal snrtace, and a corresponding surface 25 oit the smokebox, which rests upon it, is a plane surface. This is preferred, as itia cilitates the machining and fitting together ot' these parts. Themachining oli the snri'aee 25 is further facilitated by mal/:ing theiront and rear tlanges 22 separated trom the side flanges 23 by spaces26 (see Fig. Q).

The smoke boi; presents an oiiiening' 2T for an exhaust pipe 28. ln thepresent instance, t'ront and rear tlanpes have a length not greater thanthe horizontal dimension ot this opening, transversely of the smokebox,and the side flanges have a length no greater than the horizontaldimension ot the opening longitudinally of the smoke box. Thisconstruction permits the surface 25 to be machined conveniently byplaning,

or by the use ot a milling cutter, as Will be evident from anexamination of Fig. Q. The smoke box is suitably secured to the cylindersaddle, as by bolts Q9 having` nut-s 30, which are on the outside oitthe smoke box Where they are n-ot subject to the abrasive and corrcsiveaction oit the cylinders and products et con'ibnstion, and where theyare readily accessible tor removal in case at any time it should becomenecessary or desirable to remove the smoke .box trom its seat. on thecylinder saddle.

This application is a division of my pendi application tor locomotivesmoke boxes and dratt appliances, Ser. No. 13,242, tiled March 5, 1925.

Havingl thus described one embodiment oi the invention, but Withoutlimiting myseltl thereto, what l claim and desire by Letters Patent tosecure is:

l. in a locomotive, the combination ot a cylinder saddle and a smoke-boxinterengaging with each other and held against relae tive displacementin a horizontal direction by reason ot their interengagement, and meansrigidly attaching said smoke-box to said saddle.

Q. ln a locomotive, the combination of a cylinder saddle and asmoke-box, one presenting abutments by which the other is held againstdisplacement in a horizontal direction relatively thereto, and means tohold said saddle and smoke-box against relative vertical displacement.

In a locomotive7 the combination of a saddle and a smoke-box, the latterpresenting front and rear abutments between which a portion of theformer is received.

4. In a locomotive, the combination ot a steam pipe, a cylinder saddlesecured to said pipe, and a smolte-box connected with said pipe andinterengaging with said saddle and held thereby againstdisplacementhorizontally both longitudinally and transversely of the locomotive andin turn holding,` said pipe against horizontal displacement.

5. In a locomotive, the combination of a saddle and a smoke-box, onepresent-ingl abutments by Which the other is held against. displacementin a horizontal direction longt tndinally ot the locomotive, and onepresentingV abntments by which the other is held against displacement ina horizontal direction transversely ot' the locomotive.

6. In a locomotive, the combination of a saddle and a smoke-box,presenting troni: and rear and lateral abutting `surfaces by which saidsaddle and smoke-box are held against relative horizontal displacementboth longitudinally and transversely of the locomotive. i

7. In a locomotive, the combination ot a saddle and a smoke-box, thelatter presenting front and rear and side flanges between which aportion of said saddle is received and by which relative horizontaldisplacement ol said saddle and smoke-box 1ongitndinally andtransversely of the locomotive is prevented.

8. In a locomotive, the combination oit a cylinder saddle and asmoke-box having plane surfaces, one resting on the other, and meansrigidly attaching said saddle and s1nolze-box together.

Sl. In a locomotive, the combination oi' a saddle and a smolte-boxhaving plane, horizontal surfaces, one resting on the other, said saddleand smoke-box interengaging with each other and held against relativehorizontal displaceniient in every direction by reason ot' theirinterengagement.

l0. In a locomotive, the combination et a saddle and a smoke-box havingplane, horizontal surfaces, one resting on the other, one el' said partspresenting abutnients by which the other is held against horizontaldisplacev ment in every direction relatively thereto.

ll. In a locomotive, the combination ot a saddle and a smokebox havingplane, horizontal surfaces, one resting on the other, one ot said partspresenting abutments by which the other isheld against displacement in ahorizontal direction relatively thereto longitudinally of thelocomotive, and one of said parts presenting allotments by which theother is held against displacenient in a horizontal direction relativelythereto transversely olf the locomotive.

l2. In a locomotive, the combination ot a saddle and smoke-box having`plane, horizontal surfaces, one resting on the other, said smoke-boxpresenting lront and rear flanges and side `lianges between Which aportion ot said saddle is received.

In a locomotive, the combination of a saddle and a smoke-box havingplane, horizontal surfaces, one resting on the other, said smoke-boxpresenting pairs ot liront and rear and side 'flanges between which aportion ot said saddle lis received, the front and rear flanges beingseparated from the side flanges by spaces.

14. In a locomotive, the combination of a saddle and a smoke-box havingplane, horizontal surfaces, one resting on the other, said smoke-boxpresenting pairs of front and rear and side flanges between which aportion ot said saddle is received, the length of each front and rearflange being less than the dimension of said horizontal surface o't saidsmoke-box transversely oi the latter, and the length oi each side flangebeing less than the dimension el said horizontal snrtaee ol saidsmoke-box longitudinally of the latter.

l5. In a locomotive, the combination ol? a saddle having a plane,horizontal surface, and a smolte-box having an opening and a plane,horizontal surface about said opening and resting on the horizontalsurface ot said saddle, said smoke-hoi; presenting pairs ot liront andrear and side flanges einbracing a portion ot said saddle, the iront andrear lianges having a length no greater than the horizontal dimensionol' said open ing transversely olf .said snioltabox, and the side langeshaving a length no greater than the horizont-al dimension ol" saidopening longitudinally oit said sinnlichen.

lo. In a locomotive, the combination ol' a saddle and a smoke-box, thelatter present ing an opening', and a pipe .secured to said saddle andextending `through .said opening into said smoke-box, said saddle andsinnlicbox inter-engaging with each other about said opening andindependently ol said pipe and being held against relative displaceqinenthorizontally by reason ol'l their interengagement.

iT. In a locomotive, the combination ol a saddle and a sniole-box, thelatter preseiiting an opening, said saddle and snioliediox interengaging with each other about and independent-ly ollv said openingand being held against relative horizontal displacement by reason oftheir interengagemenl.

18. In a locomotive, the combination ot a saddle and a sn1ole-box, thelatter presenting an opening, said saddle and smoke-boi; interengagingwith each other about and independently ot said opening` and being heldagainst relative horizontal displacement by reason of theirinterengagen'ient, said saddle presenting a hollow projection extendinginto and spaced lrom the sides ot said opening.

In testimony whereof, I have signed my name to this specilieation.
